I tried that a few years ago would be curious how it does.

The single phase motor turned in the 1725 to 1750 range. At that rpm I could get voltage but no significant current.

I never tried it again but I think the 3 phase needed to turn a true 1800 to get current. Someone else may know more about this.

I built a 7.5 hp idler and it starts my 5 hp lath just fine on low speed. It won't start on high speed most of the time although you can start it in low and flip to high.

To start directly on high I add another 5 hp motor. Another 3 wouldn't do it. Getting the current to balance is a cut an try thing. It's like that one older guy I talk to, this is an art.
